Komura used two interchangeable mount systems.   The first was a 47mm threaded adapter similar to a T-mount.  It is called a Unidapt.   Do not confuse this with a rare Tokina adapter which is also 47mm.  The second system is called Uni Auto.  It is a bayonet system similar to Tamron Adaptall.   Both adapters can be very hard to find.  This pic was borrowed from a forum.

The Edixa m42 mount is oriented slightly off of the Praktica standard.  Lenses with aperture arms and automatic aperture lenses made by other mfg's will not work properly on an Edixa body.  Also, Edixa lenses may not work properly on standard m42 bodies.

The Modulation Transfer Function is crucial for optimizing the design of lenses and improving the manufacturing process. Engineers can use the MTF to refine designs, address aberrations or limitations, and enhance the overall quality of the captured images. Furthermore, the MTF curve allows for meaningful comparisons between different lens assemblies or imaging systems, enabling engineers to make informed decisions. By leveraging the insights provided by the MTF, manufacturers can ensure their lenses meet the desired performance standards, researchers can evaluate and advance imaging technologies, and photographers can select lenses that best suit their needs for capturing high-resolution and high-contrast images.

Modulation Transfer Function (MTF) is commonly used to qualify and evaluate the performance of imaging systems, such as lens assemblies. MTF is a useful tool for measuring and characterizing the resolution and contrast of a lens, which are key factors in determining its overall quality. The MTF curve of a lens assembly shows the degree to which the system can transfer contrast from the object to the image plane at different spatial frequencies. The MTF curve provides information about the lens' resolving power, or its ability to distinguish fine details in the image.

The Sigma mount has two variations.  The first version has two bayonets to support heavy lenses.   That feature was not actually used so they removed the extra bayonet with the introduction of the SD14.  All Sigma AF bodies use the Sigma bayonet mount.  Early Sigma MF bodies used Pentax mounts.

Petri only made one lens mount, but they also used M42 mounts.  Some Petri lenses have Pentax K mounts but they were made by third party manufacturers such as Cosina.   Petri bayonet and M42 mount lenses were excellent.   The Cosina made lenses are not the same build quality but the optics can be quite good.

The Modulation Transfer Function (MTF) is a valuable tool for manufacturers to assess the imaging capabilities of lenses and ensure they meet the desired standards for resolution and contrast. By analyzing the MTF curve, engineers can gain insights into the limitations and performance characteristics of a lens assembly.

Miranda's lens mount was originally a 44mm screw mount.. They switched to a bayonet mount for the Sensorex.  Some of their lenses have both mounts so they can be used with any Miranda body.

No imaging system is perfect, and so the MTF curve of a real system will drop off at higher spatial frequencies due to factors such as lens wavefront aberrations.

Topman made lenses in the early 1980's.   They used an aperture specific interchangeable mount.  These mounts are rare but not in high demand,.

Vivitar TX mounts look very similar to T4 mounts but they are not fully interchangeable.   T4 mounts can be used on TX lenses but TX mounts can not be used on T4 lenses.   TX mounts have slightly better automation.   T-Mounts thread onto telescopes, mirror lenses and preset lenses.  They do not offer any automation.   T2 mounts are adjustable T-Mounts.

Tamron Adaptamatic mounts attach to the lens a bit awkwardly and are tightened to the lens by way of a large retaining ring.   Adaptamatic mounts offer limited automation and can be tricky to attach.   Tamron replaced the Adaptamatic with the Adaptall system which offers more control and is much easier to attach.
